high efficiency nearly with my practical 72%..and the cross over distortion had been eleminated by the slight shift of q point above cut off region
Class AB push pull is used in battery powered amplifiers as used in radios because the current drawn reduces during quiet periods, saving battery power.

What is Class B push-pull amplifier?
When we get amplifier output current for 180 degrees of input. then it's called B class amplifier. In a push pull class B amplifier one of the two power transistors or other amplifying elements handles the positive half of the waveform and the other element handles the negative half of the waveform. In practice, push pull audio amplifiers are usually class AB; each power transistor handles slightly more than 180 degrees of input. This minimizes distortion (crossover distortion) when one of the two transistors ceases output and the other takes over.
What are the uses of complementary symmetry class B push-pull amplifier?
Sound amplification. Servo control systems.
What is the purpose of diodes in a push pull amplifier?
To bias the transistors at 0.7 Volts.
What are the advantages of push pull amplifier?
The advantage of this circuit is that there is very little current taken if there is no signal input
Is pull push amplifier is known as class b amplifier?
No, a push-pull amplifier can be built class A, class AB, class B, or class C depending on application.class A push-pull is used for low power audio usuallyclass AB push-pull is used for high power audio usuallyclass B and class C push-pull is used for very high power radio usually (B is typical for AM and C is typical for FM)

Why the name push pull is given to class B power amplifier?
Because two amplifiers are used to accomplish class B power amplifier. One is used to push the current and the other one is used to pull the current. These two amplifiers are almost same but one is connector supplied and the other one is emitter supplied.
Why Amplifier of class B has high theoretical efficiency of 78.5 percent?
The Class B amplifier is a push pull amplifier with 78.5% efficiency. The high efficiency is due to the absence of power consumption during idle time which simultaneously increases the efficiency.
Amplifiers following the modulated stage in a low level modulation am system be?
linear circuits (class B push pull power amplifier)
What advantage does the class B amplifier have over the class A amplifier?
The main advantage is lower power dissipation as the amplifier is not conducting half the time, however the resulting disadvantage is that it is nonlinear unless the more complex push-pull amplifier design is used (requiring about twice as many components).
